Description

Technical Field

[0001] The present invention relates to the technical field of film detection devices, and in particular to a camera-based full-width film detection device. Background Art

[0002] In vacuum coating equipment, the quality of the product is determined by key factors such as the width of the screen tape, the size and spacing of the fuses, whether there are impurities and spots in the coating, pattern clarity, thickening width, and whether the thickening area is in the center. In the past, the production process was mainly based on the operator's observation and experience, and after production, the results were analyzed by some detection devices, and then the parameters of the production process were adjusted.

However, long-term visual monitoring can easily lead to operator fatigue, thereby increasing the error rate. This inspection method that relies on the human eye is difficult to achieve comprehensive and real-time inspection of the entire object surface, limiting the accuracy and efficiency of the inspection.

DETAILED DESCRIPTION

[0025] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content. Example 1

[0026] The present invention discloses a camera-based full-width film detection device, such as Figure 1 As shown, it includes a bottom frame 1, a bottom plate 2 is fixedly installed inside the bottom frame 1, a programmable logic controller, a guide rail 3 and a servo motor 4 are fixedly installed on the upper surface of the bottom plate 2, the programmable logic controller is used to control the forward and reverse rotation of the servo motor 4, a sliding base 5 is slidably provided on the guide rail 3, a guide wheel 6 is provided on the lower surface of the sliding base 5, and the guide wheel 6 is set to roll along the long side direction of the sliding base 5, the output end of the servo motor 4 is connected to a screw rod 7, the screw rod 7 runs through the inside of the sliding base 5, a camera 8 is fixedly installed on the sliding base 5, the camera 8 collects a full-frame picture of the film by moving the sliding base 5 left and right, the camera 8 captures the picture by uploading it to a host computer connected to the output end of the camera 8, so as to realize real-time stitching of pictures, and analyze and detect through the algorithm of the programmable logic controller.

[0027] like Figure 1 As shown, the programmable logic controller (PLC) is responsible for controlling the forward and reverse rotation of the servo motor 4, and adjusting the movement of the sliding base 5 through program settings; the servo motor 4 drives the sliding base 5 to move left and right through the screw rod 7, and the rotation of the screw rod 7 drives the guide wheel 6 on the sliding base 5 to roll on the guide rail 3 to achieve smooth movement; the camera 8 fixedly installed on the sliding base 5 captures the full-frame image of the film in real time during the sliding process; the camera 8 can cover the entire surface of the film by moving to ensure the integrity of the image; the captured image is uploaded through the connected host computer for real-time image stitching and analysis; the programmable logic controller can use algorithms to perform quality inspection and defect analysis on the stitched image.

[0028] like Figure 1 As shown, a camera 8 is used to photograph the target, but the camera 8 can run along a path (such as moving back and forth) to gradually scan the entire width of the object to be inspected; this method can avoid the use of multiple devices and reduce the complexity and cost of the system; during the moving shooting of the camera 8, multiple images acquired in real time will be stitched together to form a large seamless image; this stitching capability means that no matter how wide the target object is, it can be fully inspected by moving the camera 8 to cover the entire format of the object to be inspected; in traditional small-scale inspections, usually only smaller areas can be inspected, and some important information is easily missed, especially for the inspection of wider objects; through the back and forth scanning of a single camera 8, the entire object surface can be effectively inspected in real time; this method solves the limitations of conventional technologies and can capture more comprehensive information.

[0029] like Figure 1 As shown, it is worth explaining in detail that the algorithm includes an eigenvalue algorithm of a picture matrix, a filtering algorithm and an NMS non-maximum suppression algorithm.

[0030] like Figure 1 As shown in the figure, eigenvalue algorithms usually involve extracting important information by calculating features in the image (such as edges, corners, etc.); commonly used eigenvalue algorithms include Harris corner detection, SIFT (scale-invariant feature transform), etc. These algorithms can identify areas with obvious features in the image; they can extract significant features in the image, which is helpful for subsequent image analysis or recognition; and they improve the accuracy of target detection because they only focus on important parts of the image without responding to background noise.

[0031] like Figure 1 As shown, the filtering algorithm is used to smooth the image, remove noise, and enhance specific features; common filtering algorithms include mean filtering, Gaussian filtering, median filtering, etc.; it helps to reduce unnecessary noise in the image and provide clearer image data, thereby improving the accuracy of subsequent processing; smoothing can reduce artifacts, enhance significant features, and facilitate subsequent feature extraction and target recognition.

[0032] like Figure 1 As shown in the figure, non-maximum suppression (NMS) is a post-processing technique mainly used in target detection tasks. It reduces duplicate detections by eliminating redundant detections between overlapping boxes and retaining the target detection results with the highest probability or score. It ensures that the final output detection box is optimal, thereby improving the accuracy of target detection. It reduces the false detection rate, makes the detection results more accurate, and helps to improve the overall performance of the model.

[0033] like Figure 1As shown, the combination of these algorithms can significantly improve the efficiency and accuracy of image processing and target detection.

[0034] like Figure 1 As shown, the system uses image processing algorithms to analyze the stitched images and can automatically identify the specific location and width of the thickened area. This process does not require human intervention and can quickly and accurately feedback the material status.

[0035] like Figure 1 As shown, specifically, the meaning of thickened area: thickened area refers to certain areas on the surface of materials or products with greater thickness, which may be caused by uneven materials, process problems, etc.; identifying thickened areas is an important part of quality control.

[0036] like Figure 1 As shown, a single camera 8 moves back and forth in the horizontal or vertical direction and takes pictures in batches; after each shooting, the system splices the newly taken image with the previous image and continues to expand it into a large image; the spliced ​​continuous images are processed by an algorithm, the thickness data of each area is extracted, and the thickened area is identified and marked; the information of the thickened area, such as the position and width, is recorded for subsequent analysis and quality control; only one camera 8 is used, which reduces equipment cost and technical complexity.

[0037] like Figure 1 As shown, through the back and forth movement of the single camera 8, the full-width image of the film can be quickly captured and processed, thereby improving the speed and efficiency of detection; the use of a high-resolution camera 8 and a precise motion control system can carefully detect subtle defects on the surface of the film and improve the accuracy of inspection; through PLC control, the operation of the equipment is automated, manual operations are reduced, work efficiency is improved, and human errors are reduced.

[0038] like Figure 1 As shown, a semi-enclosed protective block 9 is fixed to the upper surface of the sliding base 5, and the protective block 9 is located on the outside of the camera 8. The position of the protective block 9 is designed to be on the outside of the camera 8, which can effectively prevent external objects from directly impacting, colliding or scratching the camera 8 body, thereby reducing the risk of equipment damage. Example 2

[0039] like Figure 2As shown, side frames 10 are fixedly installed on the upper surfaces of both sides of the bottom frame 1, side panels 11 are fixedly installed inside the side frames 10, top frames 12 are fixedly installed on the top of the side frames 10, top panels 13 are fixedly installed inside the top frames 12, a plurality of partitioning and positioning columns 14 are evenly spaced on the lower surface of the top panel 13, and the partitioning and positioning columns 14 at equal intervals divide the lower surface of the top panel 13 into a plurality of mounting grooves 15, a plurality of cameras 8 are provided, and a plurality of the cameras 8 are installed in the mounting grooves 15 of the top panel 13. During the production process, the cameras 8 are in a fixed position inside the mounting grooves 15, and the host computer simultaneously captures a plurality of cameras 8 to realize real-time stitching, and detects the size through algorithm analysis.

[0040] like Figure 2 As shown, the device forms a stable installation platform through the combined structure of the bottom frame 1, the side frame 10, the top frame 12 and the top plate 13 to ensure the fixation and stability of the camera 8; this structure enables the camera 8 to shoot at a predetermined position, thereby ensuring the consistency and comparability of the image; the separation positioning column 14 on the lower surface of the top plate 13 provides a plurality of independent installation slots 15 in structure; this allows multiple cameras 8 to be installed on the same top plate 13 at the same time, and each camera 8 has its own independent shooting area to avoid mutual interference; during the production process, all cameras 8 shoot at their respective fixed positions, and the upper computer captures these images in real time; by synchronizing the work of multiple cameras 8, large-area rapid detection can be achieved; through the captured image data, the data shot by multiple cameras 8 can be processed simultaneously using algorithm analysis to achieve real-time stitching and measurement detection; this part usually involves image processing and data analysis technology, which can effectively extract key information.

[0041] like Figure 2 As shown, multiple cameras 8 work simultaneously, which can greatly improve the detection efficiency; compared with a single camera 8 taking pictures in sequence, the speed of the overall production process will be accelerated; because the camera 8 takes pictures at a predetermined fixed position, the error caused by position change is eliminated, ensuring the high accuracy of size detection; through real-time data processing of the host computer, the detection results can be quickly obtained, errors in the production process can be corrected in time, and product quality can be improved.

[0042] like Figure 2As shown, by capturing different parts of the photographed object at the same time by multiple cameras 8, multiple images can be stitched together in real time; since the multiple cameras 8 work independently, the areas photographed by them can overlap each other, forming a wider detection range; this means that no matter how wide the object to be inspected is, it can be fully inspected through the stitching capability of the camera 8 system, rather than being limited to a small range; in traditional inspections, only one camera 8 is often used to inspect a small area, and such inspections may miss some details or defects when the object is large or complex; by using a multi-camera 8 system, the entire surface can be inspected in detail, and both width and length can be fully covered, reducing the risk of missed inspections.

[0043] like Figure 2 As shown, the system can identify and calculate the exact location and width of the thickened area by capturing images of different areas and then using algorithms to analyze the captured image data; this process is automated, meaning that information about the thickened area can be obtained quickly and accurately without human intervention.

[0044] like Figure 2 As shown, specifically, the meaning of thickened area: refers to the increased thickness of certain products or materials in a specific area; this is usually caused by process reasons, material non-uniformity or other factors; the thickened area may affect the performance and quality of the product, so it requires special attention.

[0045] like Figure 2 As shown, multiple cameras 8 simultaneously shoot the target at different positions; the host computer stitches the captured multiple images in real time to form a complete image; through the image processing algorithm, the thickness information in the stitched image is analyzed to identify the position and width of the thickened area; the information of the detected thickened area is fed back to the system operator or recorded in the database for subsequent quality control or production adjustment. Example 3

[0046] like Figure 3 As shown, a plurality of mounting members 16 for fixing the camera 8 are provided in the mounting groove 15 on the top plate 13, and the mounting members 16 are arranged in a one-to-one correspondence with the number of cameras 8. The mounting members 16 are connected to the protective block 9 outside the camera 8, and the design of the mounting members 16 facilitates the rapid assembly and disassembly of the camera 8; when the camera 8 needs to be replaced or maintained, the operator can quickly take the camera 8 out of the mounting groove 15 or put it back in, and the rapid assembly and disassembly function makes the replacement and maintenance of the camera 8 simple and efficient, especially when frequent equipment updates or repairs are required, this design greatly saves time and labor costs.

[0047] like Figure 4 and Figure 5As shown, specifically, the mounting member 16 includes a special-shaped column 1601 fixed at the center position of the top of the protective block 9 and a positioning sleeve 1602 arranged in the top plate 13, the bottom of the positioning sleeve 1602 is provided with a special-shaped groove 1603 matching the cross section of the special-shaped column 1601, and the radial surface of the positioning sleeve 1602 is provided with a limiting hole 1604, one end of the limiting hole 1604 is opened on the inner wall of the special-shaped groove 1603, and the positioning sleeve An insert rod 1605 is slidably provided inside the limiting hole 1604 of the tube 1602, and a socket 1606 matching the insert rod 1605 is provided on the special-shaped column 1601.

[0048] like Figure 4 and Figure 5 As shown, the special-shaped column 1601 and the special-shaped groove 1603 of the positioning sleeve 1602 adopt matching special-shaped structures, which can ensure that the special-shaped column 1601 has a specific directionality during installation and avoid misalignment; after the special-shaped column 1601 is fully inserted into the special-shaped groove 1603 of the positioning sleeve 1602, the position of the limiting hole 1604 will be aligned with the insertion hole 1606; the existence of the limiting hole 1604 is mainly used to provide accurate positioning and ensure the correct insertion of the insertion rod 1605; when the insertion rod 1605 is pressed, the insertion rod 1605 will slide into the junction of the limiting hole 1604 and the insertion hole 1606 to achieve a locking effect; in this way, under pressure, the insertion rod 1605 can maintain the fixed state of the special-shaped column 1601 to prevent it from slipping or falling off during use.

[0049] like Figure 4 and Figure 5 As shown, a baffle 1607 is fixedly installed on the outer surface of the positioning sleeve 1602, and a rotatable shaft 1608 is provided on the baffle 1607. A pressing plate 1609 is provided on the rotating shaft 1608. The middle part of the pressing plate 1609 is connected to the rotating shaft 1608, and a clamping head 16010 is fixedly installed on one end of the pressing plate 1609. The clamping head 16010 matches the clamping groove 16011 set on the surface of the insertion rod 1605. The other end of the pressing plate 1609 is connected to the outer surface of the positioning sleeve 1602 through a spring 16012. When in use, the pressing plate 1609 is rotated around the central axis of the rotating shaft 1608 by pressing one end of the pressing plate 1609 close to the spring 16012. At this time, the clamping head 16010 is driven to move inside the clamping groove 16011 to control the sliding of the insertion rod 1605 inside the socket 1606.

[0050] like Figure 4and Figure 5 As shown, the other end of the pressing plate 1609 is connected to the outer surface of the positioning sleeve 1602 by a spring 16012, which plays a restoring role; when the pressing plate 1609 is pressed, the spring 16012 will maintain a certain tension to ensure that the pressing plate 1609 can quickly return to its position after being released; the clamping head 16010 is fixed at one end of the pressing plate 1609 and can cooperate with the clamping groove 16011 on the surface of the insertion rod 1605; when the pressing plate 1609 rotates, the clamping head 16010 moves in the clamping groove 16011, thereby controlling the sliding position of the insertion rod 1605 in the insertion hole 1606; by controlling the pressing plate 1609, the sliding position of the insertion rod 1605 can be accurately adjusted, thereby realizing the control of the locking or release mechanism of the special-shaped column 1601.

[0051] like Figure 5 and Figure 6 As shown, a protective cover 17 is fixedly installed on the upper surface of the top plate 13, and the protective cover 17 is located outside the plurality of mounting parts 16. A revolving door 18 is provided on the protective cover 17, which is used to protect the outside of the plurality of mounting parts 16 and avoid accidental contact with the pressing plate 1609 on the mounting parts 16.

[0052] Working principle: When in use, the servo motor 4 drives the sliding base 5 to move left and right through the screw rod 7. The rotation of the screw rod 7 drives the guide wheel 6 on the sliding base 5 to roll on the guide rail 3 to achieve smooth movement; the single camera 8 fixedly installed on the sliding base 5 captures the full-frame image of the film in real time during the sliding process; the camera 8 can cover the entire surface of the film by moving to ensure the integrity of the image; the captured image is uploaded through the connected host computer for real-time image stitching and analysis; the programmable logic controller can use algorithms to perform quality inspection and defect analysis on the stitched image.

[0053] Before use, several fixed-position cameras 8 are fixed in the mounting groove 15 of the top plate 13 through the mounting parts 16. In traditional inspections, only one camera 8 is often used to inspect a small area. Such inspections may miss some details or defects when the object is large or complex. By using a multi-camera 8 system, the entire surface can be inspected in detail, covering all widths and lengths, reducing the risk of missed inspections.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
